L' effet photo-électrique des rayons X dans les gaz
This paper is foundational for understanding the Auger effect, a phenomenon where an atom with an inner-shell vacancy de-excites by ejecting an electron rather than emitting an X-ray photon. Auger's detailed analysis of the photoelectric effect of X-rays in gases led directly to his discovery and explanation of this process, which is now named after him.
This work represents a pivotal moment in Pierre Auger's career, as it laid the groundwork for his most famous discovery, the Auger effect. His subsequent research built upon these initial investigations into X-ray interactions with matter, solidifying his legacy in atomic and nuclear physics.
